To find this data for your blog(s), put the following line in XMLRPCEncoder.m : -encode just before the return statement at the end of the method. Put a breakpoint on that line, then compile the app, and delete and re-add your blog. Continue through the breakpoint several times (one for each different method call to the WP Server) and you will get the wp.getPages call on the 6th or 7th try.

The NSLog line will output the XML being used to build the XMLRPC request... You can then use copy/paste that into an HTTP client tool to test.
